Filed: 2001-10-30
Abstract: PROBLEM TO BE SOLVED: To make it difficult or impossible to estimate information processed in an information processor by observing the consumption current and radiated electromagnetic wave of the information processor. SOLUTION: If a value stored in b[0] is now read, an output from a random number generating device is used to exchange storage positions between b[0] and any of b[1] to b[3] with 3/4 probability. The probability of selecting b[1] to b[3] as an object for exchanging storage positions by using an output of the random number generating device is made to be respectively 1/3. For example, in the case that b[0] is replaced with b[1] as shown from the state of E1501 to that of E1503 in figure 15, b[2] is further replaced with b[3]. If b[0] is similarly replaced with b[2], b[1] is replaced with b[3] (E1504), and if b[0] is replaced with b[3], b[1] is replaced with b[2] (E1505), By following this procedure, in the case that b[0] is reaccessed, the probability that data of b[0] is the same as data of the previous b[0] is 1/4.
